Description

Technical Field

[0001] This application relates to the field of ear cover manufacturing, and in particular to an ear cover folding machine. Background Technology

[0002] Headphones consist of ear shells, head arches, and telescopic headbands. The ear shells and head arches are usually covered by ear tips, which are mainly used to protect the headphones and improve wearing comfort. The ear tips consist of an outer skin and an inner plate. The inner plate is coated with glue, and the outer skin is bent and fitted onto the inner plate in conjunction with the glue on the inner plate.

[0003] In existing related technologies, the outer skin and inner plate are placed on the ear cup holder, the inner plate is fixed by pressing down with a pressure block, and then the outer skin of the ear cup is folded by a folding block, that is, the outer skin of the ear cup is bent towards the inner plate. The outer skin of the ear cup is then fixed to the inner plate, and the inner plate of the ear cup is glued to the pressure block.

[0004] Regarding the aforementioned technologies, since the inner plate is glued to the pressure block, it is not convenient to separate the completed ear cover from the pressure block. Summary of the Invention

[0005] To address the issue of ear covers sticking to the pressure block due to glue on the inner plate, this application provides an ear cover folding machine.

[0006] The ear cover folding machine provided in this application adopts the following technical solution:

[0007] An ear cover folding machine includes a mounting frame, a pressing component, and a folding component. The mounting frame is equipped with an ear cover placement seat, which is used to place ear covers.

[0008] The pressing assembly includes an ear cup pressing block and an ear cup separating plate. The ear cup pressing block is used to apply vertical pressure to the ear cup placed in the ear cup placement seat, and the ear cup separating plate slides vertically to engage with the ear cup pressing block.

[0009] When the ear sleeve pressing block is close to the ear sleeve placement seat, the ear sleeve separation plate is fitted with the ear sleeve with a clearance;

[0010] When the ear sleeve pressing block is away from the ear sleeve placement seat, the ear sleeve separating plate abuts against the ear sleeve;

[0011] The folding assembly is used to fold the edges of the ear covers.

[0012] By adopting the above technical solution, the earbud pressing block applies vertical pressure to the outer skin and inner plate of the earbud placed in the earbud holder, ensuring that the earbud pressing block can fully press the inner plate of the earbud. When the earbud outer skin is folded with the folding assembly, the earbud separating plate and the earbud maintain a gap fit. The earbud outer skin is bent to the inner plate by the folding assembly. When the earbud pressing block moves away from the earbud holder (i.e., is lifted upward), the earbud separating plate will abut against the folded part of the earbud outer skin and the inner plate due to the vertical sliding fit between the earbud separating plate and the earbud pressing block. This allows the earbud separating plate to push out the earbud that is stuck to the earbud pressing block due to glue, so that the folded earbud can be easily separated from the earbud pressing block.

[0013] Optionally, the ear cover holder can be detachably mounted on the mounting frame.

[0014] By adopting the above technical solution, when the earbud holder becomes worn, damaged, or requires cleaning due to long-term use, it can be detached for easy and quick replacement or cleaning. Furthermore, the appropriate earbud holder can be replaced for different sizes and shapes of earbuds.

[0015] Optionally, the ear cover holder is provided with an ear cover groove for placing the ear cover.

[0016] By adopting the above technical solution, the ear cup groove provides a specific accommodating space with a matching shape for the ear cup, so that the ear cup groove can provide stable support for the outer skin and inner plate of the ear cup. This ensures that when the pressure is applied by the pressing component and the folding component performs the folding, the occurrence of ear cup folding displacement caused by the positional misalignment of the outer skin and inner plate of the ear cup is reduced.

[0017] Optionally, the mounting frame is equipped with a pressing cylinder, the piston rod of the pressing cylinder is arranged in a vertical direction, and the ear sleeve pressing block is installed on the piston rod of the pressing cylinder.

[0018] By adopting the above technical solution, by setting a pressure block cylinder on the mounting frame, the ear sleeve pressure block is installed on the piston rod set in the vertical direction, so that the ear sleeve pressure block can smoothly apply uniform vertical pressure to the outer skin and inner plate of the ear sleeve, ensuring a stable fit between the inner plate and the outer skin of the ear sleeve.

[0019] Optionally, the ear cup pressing block matches the shape of the ear cup groove, and when the ear cup pressing block applies vertical pressure to the ear cup placed on the ear cup placement seat, the periphery of the ear cup pressing block is in clearance fit with the inner wall of the ear cup groove.

[0020] By adopting the above technical solution, by making the shape of the earphone sleeve pressing block match the shape of the earphone sleeve groove, when the earphone sleeve pressing block applies a vertical pressure to the earphone sleeve placed on the earphone sleeve placement seat, the gaps between the four sides of the earphone sleeve pressing block and the inner wall of the earphone sleeve groove are in clearance fit, so as to ensure that the outer skin and the inner plate of the earphone sleeve can be stabilized during the downward pressing process, and reduce the occurrence of the offset between the outer skin and the inner plate of the earphone sleeve.

[0021] Optionally, the earphone sleeve separation plate is provided with a separation groove penetrating therethrough, and the earphone sleeve pressing block slides through the separation groove of the earphone sleeve separation plate. When the earphone sleeve pressing block does not apply a vertical pressure to the earphone sleeve placed on the earphone sleeve placement seat, the earphone sleeve pressing block is embedded in the separation groove of the earphone sleeve separation plate;

[0022] When the earphone sleeve pressing block applies a vertical pressure to the earphone sleeve placed on the earphone sleeve placement seat, the earphone sleeve pressing block is away from the separation groove of the earphone sleeve separation plate.

[0023] By adopting the above technical solution, when the earphone sleeve pressing block moves downward to apply a vertical pressure to the earphone sleeve placed on the earphone sleeve placement seat, the earphone sleeve pressing block will continue to move downward through the separation groove of the earphone sleeve separation plate, and the earphone sleeve pressing block will extend and be away from the separation groove of the earphone sleeve separation plate. At this time, a relative displacement occurs between the earphone sleeve pressing block and the earphone sleeve separation plate, and the earphone sleeve separation plate will not contact or interfere with the hemming of the outer skin of the earphone sleeve, so that the hemming component can bend the outer skin of the earphone sleeve onto the inner plate, thereby fitting the outer skin and the inner plate of the earphone sleeve. When the earphone sleeve is hemmed by the hemming component and the earphone sleeve pressing block moves upward (i.e., does not apply pressure to the earphone sleeve), the earphone sleeve pressing block will retract and be embedded in the separation groove of the earphone sleeve separation plate, and the earphone sleeve separation plate will抵触 with the part of the outer skin and the inner plate of the earphone sleeve where the hemming is done, and then eject the earphone sleeve adhered to the earphone sleeve pressing block due to glue from the earphone sleeve pressing block, so as to smoothly separate the earphone sleeve pressing block from the earphone sleeve.

[0024] Optionally, the hemming component includes a plurality of first hemming blocks, a plurality of second hemming blocks and a plurality of hemming driving members. The plurality of first hemming blocks surround the earphone sleeve placement seat and are farther from the corners of the earphone sleeve placement seat than the plurality of second hemming blocks, and the plurality of first hemming blocks are distributed in a "cross" shape;

[0025] The plurality of second hemming blocks surround the earphone sleeve placement seat and are closer to the corners of the earphone sleeve placement seat than the plurality of first hemming blocks, and the plurality of second hemming blocks are distributed in a "square" shape. The plurality of hemming driving members are used to drive the plurality of first hemming blocks and the plurality of second hemming blocks to move in the direction close to the earphone sleeve groove.

[0026] By adopting the above technical solution, several first folding blocks first bend the main four sides of the earbud outer skin, and then several second folding blocks bend the corner areas of the earbud outer skin, ensuring that the earbud outer skin can be bent evenly and tightly around the inner plate. The folding drive first drives several first folding blocks, and then drives several second folding blocks to move towards the earbud groove of the earbud placement seat, realizing a step-by-step coordinated earbud folding.

[0027] Optionally, a plurality of the first folding blocks and a plurality of the second folding blocks are detachably mounted on the folding drive.

[0028] By adopting the above technical solutions, we can adapt to diverse production needs and increase the versatility of the equipment by producing ear covers of different specifications and shapes.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The ear sleeve separation plate and the ear sleeve pressing block slide vertically together. When the ear sleeve pressing block is pressed down to apply pressure, the ear sleeve separation plate and the ear sleeve maintain a clearance fit to ensure that the ear sleeve pressing block can fully press the inner plate of the ear sleeve. When the ear sleeve pressing block is lifted up, the ear sleeve separation plate abuts against the ear sleeve, thereby pushing out the ear sleeve that is stuck to the ear sleeve pressing block with glue, so as to facilitate the smooth separation of the ear sleeve and the ear sleeve pressing block.

[0031] 2. The earbud holder features an earbud groove, providing a specific shaped space for the earbud to accommodate it, ensuring stability during pressing and folding, and reducing misalignment during folding. Simultaneously, the earbud clamping block matches the shape of the earbud groove, with gaps between its sides and the inner wall of the groove, further enhancing the stability and precision of the earbud during pressing, ensuring a tight fit between the inner plate and the outer skin.

[0032] 3. The ear tip holder is detachable for easy cleaning. It also allows for easy replacement of the appropriate ear tip holder for different sizes and shapes of ear tips, improving the adaptability and versatility of the folding machine.

[0033] 4. A series of first and second folding blocks are driven by a folding drive unit to move towards the ear sleeve groove, achieving coordinated and step-by-step ear sleeve folding. The first and second folding blocks are detachably mounted on the folding drive unit to adapt to diverse production needs and enhance the versatility of the folding machine.

[0040] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0041] This application discloses an ear cover folding machine. (Refer to...) Figure 1 and Figure 2 The earbud folding machine includes a mounting frame 1, a pressing assembly 2, and a folding assembly 3. The mounting frame 1 is equipped with an earbud placement seat 11, which is detachably mounted to the mounting frame 1 by bolts, allowing for easy and quick removal, replacement, or cleaning. Furthermore, the earbud placement seat 11 can be replaced with the appropriate one for earbuds of different sizes and shapes. The earbud placement seat 11 has an earbud groove 101, which is designed to hold the earbud and is shaped to match the earbud's shape, providing a specific, matching space for the earbud and thus stabilizing the earbud to be folded.

[0042] The mounting frame 1 is fixedly equipped with a pressure cylinder 12. The piston rod 13 of the pressure cylinder 12 is arranged vertically downwards. The pressing assembly 2 includes an ear sleeve pressure block 21 and an ear sleeve separation plate 22. The ear sleeve pressure block 21 is fixedly installed on the piston rod 13 of the pressure cylinder 12, and the ear sleeve pressure block 21 is arranged vertically opposite the ear sleeve groove 101 of the ear sleeve placement seat 11, so that the ear sleeve pressure block 21 can apply pressure to the inner plate of the ear sleeve groove 101 in the vertical direction. When the ear sleeve pressure block 21 moves vertically toward the ear sleeve placement seat 11 and applies vertical pressure to the ear sleeve, the shape of the ear sleeve pressure block 21 matches the ear sleeve groove 101, and the periphery of the ear sleeve pressure block 21 is in clearance fit with the inner wall of the ear sleeve groove 101, so as to reduce the occurrence of misalignment between the ear sleeve outer skin and the inner plate, thereby fixing the ear sleeve outer skin and the inner plate in the ear sleeve groove 101.

[0043] The earphone sleeve separation plate 22 is provided with a separation groove 201 running through it. The earphone sleeve pressing block 21 is slidably inserted into the separation groove 201, and the pressing block cylinder 12 causes the earphone sleeve pressing block 21 to extend or retract from the separation groove 201. The relative displacement between the earphone sleeve pressing block 21 and the separation groove 201 of the earphone sleeve separation plate 22 will cause the earphone sleeve adhered to the earphone sleeve pressing block 21 by glue to be pushed downward by the earphone sleeve separation plate 22 and separated from it.

[0044] Specifically, a push rod 23 is fixedly installed on the earphone sleeve separation plate 22. The push rod 23 is slidably engaged with the earphone sleeve separation plate 22 in the vertical direction. A spring 24 is sleeved on the push rod 23, and the two ends of the spring 24 are respectively installed on the earphone sleeve separation plate 22 and the push rod 23. The mounting frame body 1 is fixedly installed with a top plate 14. The top plate 14 is located at the top of the push rod 23. The top plate 14 is provided with a notch through which the earphone sleeve pressing block 21 passes and is smaller than the earphone sleeve separation plate 22. When the earphone sleeve separation plate 22 and the push rod 23 are abutted against the top plate 14 upward, the spring 24 is compressed to slow down the impact caused by the collision. The earphone sleeve pressing block 21 moves upward relative to the separation groove 201 of the earphone sleeve separation plate 22, causing the earphone sleeve separation plate 22 to contact the part where the outer skin and the inner plate of the earphone sleeve are folded. Thus, due to gravity and the elastic force generated by the reset of the spring 24, the earphone sleeve adhered to the earphone sleeve pressing block 21 by glue is ejected from the earphone sleeve pressing block 21, thereby achieving the smooth separation of the earphone sleeve pressing block 21 and the earphone sleeve.

[0045] Refer to Figure 3 , the hemming assembly 3 includes a plurality of first hemming blocks 31, a plurality of second hemming blocks 32 and a plurality of hemming driving members 33. The plurality of first hemming blocks 31 and the plurality of second hemming blocks 32 are respectively slidably arranged on the plurality of hemming driving members 33 through key grooves, and the plurality of first hemming blocks 31 and the plurality of second hemming blocks 32 are respectively installed on each hemming driving member 33 through bolts inserted into the key grooves, so as to facilitate the sliding adjustment of the positions of the plurality of first hemming blocks 31 and the plurality of second hemming blocks 32 by loosening the bolts.

[0046] A plurality of first hemming blocks 31 surround the earphone sleeve placing seat 11 and are farther from the corners of the earphone sleeve placing seat 11 compared to the second hemming blocks 32. Refer to Figure 4 , the plurality of first hemming blocks 31 are distributed in a "cross" shape, so as to facilitate hemming the main four sides of the outer skin of the earphone sleeve. Refer to Figure 5 , a plurality of second hemming blocks 32 surround the earphone sleeve placing seat 11 and are closer to the corners of the earphone sleeve placing seat 11 compared to the first hemming blocks 31, and the plurality of second hemming blocks 32 are distributed in a "square" shape, so as to facilitate hemming the four corners of the outer skin of the earphone sleeve. Through the sequential cooperative work of the plurality of first hemming blocks 31 and the plurality of second hemming blocks 32, it is convenient to gradually and evenly bend the outer skin of the earphone sleeve along the circumference of the inner plate.

[0047] Several folding drive components 33 are used to drive several first folding blocks 31 and several second folding blocks 32 to move toward the ear sleeve groove 101. When the ear sleeve pressing block 21 is pressed against the inner plate of the ear sleeve, the ear sleeve separating plate 22 is fitted with the ear sleeve with a gap so that the several first folding blocks 31 and several second folding blocks 32 have sufficient gap space to bend the outer skin of the ear sleeve toward the inner plate.

[0048] When folding the ear tips, the inner plate is first pressed down and fixed by the ear tip pressing block 21. Then, several folding driving components 33 move several first folding blocks 31 toward the ear tip groove 101 of the ear tip placement seat 11, thereby folding the outer skin around the ear tip. Subsequently, while resetting the several first folding blocks 31, several second folding blocks 32 move toward the ear tip groove 101 of the ear tip placement seat 11 by several folding driving components 33, thereby folding the outer skin at the four corners of the ear tip. By folding the four sides first and then the four corners, the occurrence of wrinkles in the ear tip outer skin is reduced.

[0049] The implementation principle of the ear cover folding machine in this application embodiment is as follows:

[0050] First, place the inner plate with the ear cover skin already attached into the ear cover groove 101 of the ear cover placement seat 11. Then, drive the ear cover pressing block 21 to apply pressure to the ear cover skin and inner plate in a vertically downward direction through the pressing block cylinder 12.

[0051] Subsequently, several first folding blocks 31 are moved toward the ear cup groove 101 of the ear cup placement seat 11 by several folding drive components 33, and the four sides of the ear cup skin are folded. Then, while several first folding blocks 31 are reset, several second folding blocks 32 are moved toward the four corners of the ear cup groove 101 of the ear cup placement seat 11 by several folding drive components 33, and the four corners of the ear cup skin are folded.

[0052] Finally, driven by the pressure block cylinder 12, the ear sleeve pressing block 21 moves away from the ear sleeve placement seat 11. When the ear sleeve separating plate 22 and the push rod 23 abut against the top plate 14, the ear sleeve pressing block 21 slides relative to the separation groove 201 of the ear sleeve separating plate 22 and moves upward, so that the ear sleeve separating plate 22 abuts against the part of the ear sleeve outer skin and inner plate folded edge, thereby pushing the ear sleeve that is glued to the ear sleeve pressing block 21 out of the ear sleeve pressing block 21.

[0053] Therefore, this application utilizes the ear sleeve groove 101 of the ear sleeve placement seat 11 and the ear sleeve pressing block 21 to fix the inner plate of the ear sleeve when the ear sleeve pressing block 21 is pressed against it. The ear sleeve separation plate 22 is fitted with the ear sleeve with a gap so that the first folding block 31 and the second folding block 32 have sufficient gap space to bend the ear sleeve skin towards the inner plate. The ear sleeve skin is bent to the inner plate by the first folding block 31 and the second folding block 32 in sequence. The four sides and four corners of the ear sleeve skin are bent to the inner plate in sequence to reduce the occurrence of wrinkles on the ear sleeve skin.

[0054] Finally, when the ear cup pressing block 21 is driven away from the ear cup placement seat 11 by the pressing block cylinder 12 (i.e., lifted upward), the ear cup separating plate 22 and the push rod 23 abut against the top plate 14, so that the ear cup pressing block 21 moves upward relative to the separation groove 201 of the ear cup separating plate 22, thereby causing the ear cup separating plate 22 to abut against the part of the ear cup outer skin and inner plate folded edge, pushing the ear cup that is stuck to the ear cup pressing block 21 due to glue onto the ear cup pressing block 21, thus separating the ear cup pressing block 21 from the ear cup.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
